Why Size Matters: an Evaluation of Gastric Pouch Size in Roux-en-Y Gastric Bypass Using CT Volumetric Analysis and its Effect on Marginal Ulceration.
Article in Obesity surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 20 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeMarginal ulceration (MU) is a common long-term complication following Roux-en-Y gastric bypass (RYGB). The causes of MU after RYGB are multifactorial and include surgical technique of constructing the gastrojejunal anastomosis (GJA). The purpose of this study is to evaluate the relationship between gastric pouch size in RYGB and MU using CT volumetrics. MATERIAL AND
methodsPatients were retrospectively identified who underwent esophagogastroduodenoscopy (EGD) following RYGB at a tertiary care teaching hospital. Measurement of gastric pouch size was performed using 3-D CT software. Standard statistical methods were used, a univariate comparison was performed between MU and non-MU patients followed by a propensity-matched comparison to control for factors known to affect MU, and a propensity-matched subgroup analysis was also performed.
resultsIn total, 122 patients met criteria, 57 of which had MU on EGD and 65 who did not. The MU group had more smokers and patients with PPI use than the non-MU group, and the mean time from operation to CT scan was 26.6 months (range: 0-108 months). The MU group had a larger gastric pouch size than the non-MU group (34.1 ± 11.8 versus 20.1 ± 6.8 cm
conclusionsCT volumetric analysis demonstrated that a larger gastric pouch size was associated with MU following RYGB.
